3mm Opal 040 Perspex Sheet (600 x 400 mm)

Our 3mm Opal 040 Perspex Acrylic Sheet in a handy 600 x 400 mm size is a popular choice for laser cutting and engraving projects that need a clean, diffused finish with excellent light transmission.

The Opal 040 grade offers a perfect balance of light diffusion and opacity. While not fully transparent, it allows approximately 37% light transmission, making it ideal for backlit signage, illuminated displays, lightboxes, and decorative panels where a soft glow is desired without seeing the internal components behind.

This acrylic sheet cuts cleanly with laser machines, and the opal white finish provides a smooth, professional look straight off the bed. It’s also UV-resistant, durable, and lightweight – perfect for both indoor and outdoor use.
